With the Red Bulls playing their final preseason match against Club Atlas de Guadalajara tomorrow, and the opener against Seattle looming just two weeks away, coach Hans Backe still hasn’t decided who’ll be his starting keeper: Incumbent Bouna Coundoul, or challenger Greg Sutton?

“They’re about the same. They’re so even,’’ said Backe, who admitted today that Coundoul isn’t 100 percent healthy and may require an injection in the same knee that troubled him last season. “It could also be Bouna needs injection in his knee. It would probably keep him out for a week. It’s the same one as last year. If he gets the injection it will keep him out for about five days.’’

Coundoul was the starter last season, keeping 11 clean sheets to set both a personal best and shatter Tony Meola’s team record. But Backe wasn’t overjoyed that Coundoul missed a chunk of training camp to travel with the Senegalese National Team, and has praised the play of Sutton in his stead.

Sutton has always been the steadier of the two, and the lack of distance on Coundoul’s goal kicks has been an ongoing problem. But he’s the more athletic player, able to get to shots the Canadian National teamer would have no chance at. His career 1.13 goals-against average is fourth-best all-time in MLS, and his 74.6 save percentage is third in league history.

The Red Bulls are playing Dallas at 6 p.m. today, but that will be a reserve game. Coundoul will play with the reserve-heavy lineup, Sutton will go tomorrow with the starters, and then Backe will make his decision next week _ one that he says will likely be more of a permanent one, rather than a goalkeeping timeshare.

“Bouna is playing today, then next week I’ll make a decision on who could be the starter,’’ said Backe. “Normally when I take my decision (it’s final).’’
